Question

Calculate the value of the current drawn from a 5v battery

Answer 1

Answer:

I =  0.5 A

R is not given suppose R = 10 ohm

Explanation:

I = V / R    R is not given suppose R = 10 ohm

I = 5 / 10

I = 0.5 A

Answer 2

$\huge\rm\underline\purple{Question :-}$

Calculate the value of the current drawn from a 5v battery in the circuit as shown.

$\huge\rm\underline\purple{Answer :-}$

$\red{\underline\bold{To\:Find,}}$

• Value of the current = ?

✏ From the circuit diagram, (refer to the above attachment.)

✏ No current flows through the resistor 10Ω between the points B and C.

$\pink{\underline\bold{The\: resistance\: of\: arm\: ACD,}}$

R1 = 10 + 20

= 30Ω

$\pink{\underline\bold{The\: resistance\: of\: arm\: ABD,}}$

R2 = 5 + 10

= 15Ω

✏ Equivalent resistance,R = $\frac{R1×R2}{R1+R2}$

= $\frac{30 × 15}{30 + 15}$

= $\frac{30 × 15}{45}$

= 10Ω

$\orange{\underline\bold{Now,}}$

Current drawn from the source,

$\boxed{ \sf \red{I = \frac{V}{R} }}$

I = $\frac{5}{10}$

I = $\frac{1}{2}$

I = 0.5 A
